Where are sprinklers required in vertical
shafts, stairways, elevator equipment rooms and elevators shafts? The special
situations included in NFPA 13 sections 8.15.2, 8.15.3, 8.15.4 and 8.15.5 will
be reviewed.NFPA 13 requires sprinkler
protection in vertical shafts having exposed combustible construction. The
basic requirements for installation of sprinklers, considerations for
inspection and conditions allowing omission of protection in vertical shafts
will be identified. Sprinkler protection requirements for stairways of combustible,
limited combustible and noncombustible construction will be identified.
Situations involving vertical openings for escalators, staircases and atriums
will be reviewed. Sprinkler protection requirements for elevator equipment
rooms and shafts will be identified. These requirements have evolved over the
last several cycles and reviewed to demonstrate when sprinkler protection is
required and when it can be omitted.
